She said: "I don’t do drugs, I don’t deal drugs, so why was the Drug Squad storming through my home like I was running a cartel?

"I’m not into conspiracy theories. I’d like to think the fact I’ve been unfairly targeted by the police has nothing to do with the fact my book is about to be published, which happens to be very embarrassing for the Chancellor.

"There are serious questions I want answers to – Why did one officer involved in the raid ask me whether I was about to publish my memoirs and Why did a police inspector tell me I’d be opening a ‘whole can of worms’ if I complained?"

Police stayed for two hours but no drugs were found and no arrests were made.

Osborne was photographed as a young man with Rowe who went under the name Mistress Pain when she was a dominatrix.

She alleges that what appears to be a white powder on the table next to them is in fact cocaine.

When the photo was published Osborne admitted meeting Rowe but denied any associations with drug taking.

She said: "The point I’m trying to make is this, he’s a Chancellor and he should come out and tell the truth. At the end of the day, if you want to make laws and rules about drug-taking, you can’t be a hypocrite and he is.

"I told the truth consistently and I get quite offended when nobody seems to see the point that I’m trying to make which is George Osborne runs the economy and it doesn’t matter that it was in his past, the fact is that he denies it and not only does he deny it but he’s trying to portray me as someone who isn’t telling the truth and I have the right to defend myself.”
